Evidence chain connecting site facts, classification, design basis, product evidence and approval
Read a detailed text description

Five linked blocks run from project address and site facts to legal classification, adopted design basis, product-specific evidence and final approval or inspection records. Feedback arrows show that a mismatch in configuration, location or assumptions must be resolved rather than skipped by relying on a generic certificate.

Jurisdiction first: classification and adopted rules come before generic product claims. Original diagram by Pergola Wiki.

Key takeaways

The claim register connects stable IDs, article locations and article-level associated sources; it is not an external fact-check of each statement.

Model code vs law

The IRC and IBC are model codes. States and local governments choose editions, amendments and appendices. Appendix BF or Appendix I provisions only apply where incorporated into the governing rules.

Permit package

Authorities may request a site plan, dimensions, setbacks, product documents, foundation details, structural calculations and electrical information. Attached structures can require evidence about the existing building.

Model code, adoption and permit are different questions

The IRC and IBC are model codes. A state or locality may adopt an edition with amendments, use separate zoning rules and require permits at thresholds unrelated to the product name. Verify the adopted edition, structural design criteria, zoning, historic or community rules, contractor licensing and inspection stages.

Prepare an approval-ready package

A useful submission identifies site plan, property lines, setbacks, dimensions, roof openness, attachment, elevations, foundations, structural design criteria, materials, electrical work and drainage discharge. Manufacturer drawings are inputs, not automatically project drawings. Changes after approval should be documented before concealment or inspection.

Separate approval layers and submit an answerable fact pattern

Zoning review addresses location, setbacks, height and lot coverage; building review addresses structure, fire, egress and weather; electrical or fuel-gas permits can apply separately. An exemption at one layer does not remove the others. Provide the address, survey, dimensions, roof openness, attachment, enclosure, utilities, nearby openings, product documents, design criteria, foundations and use. Asking only whether a pergola needs a permit omits the controlling facts. Retain written interpretations and reassess later roofs, screens, heaters or solar equipment against the same approved description.
